Term
What does the Lymphatic System consist of?
Definition

 

consists of:

 

lymphatic capillaries

lymphatic vessels

lymphatic nodes

lymphatic ducts

Term
What are the Lymphatic organs/nodes?
Definition

 

Tonsils

Spleen

Thymus gland

Peyer’s patches (intestine)

Red bone marrow

Term
Functions of the Lymphatic System
Definition

 

1.     Return of lymph tissue excess to the blood.

 

2.     Absorption of fats and vitamins in lymph vessels

 

3.     Help defend the body against disease.

Term
What is Interstitial fluid?
Definition

At capillaries some fluid leaks out into tissue spaces.

 

This fluid needs to be returned to maintain blood volume

Non returned fluid = OEDEMA

Term
What are Lymphatic Vessels made up of/do?
Definition

 

- Similar in size and structure to blood capillaries

- pick up the excess fluid from tissue spaces and return to blood

- lymph capillaries to collecting vessels to venous system -  one way system to heart

- Small debris, viruses, bacteria etc that can’t enter blood can enter Lymph - eg cancer cells carried this way

 

- Collect excess tissue fluid- walls are a  thin layer epithelium & have large pores

 

 

- Like veins have valves to prevent back flow

Term
What are the two large ducts in the Thoracic Region?
Definition

 

Right lymphatic duct

drains lymph from right arm & right side of head & thorax

Thoracic duct

drains lymph from rest of body

 

Both ducts empty into left & right subclavian vein.

The Tonsils

 

A. Pharyngeal Tonsil

B. Platelet

C. Palantine Tonsil

D. Lingual Tonsil

Term
What does the Palatine tonsil do?
Definition

 

Small masses of lymphatic tissue surrounding the pharynx – Palatine.

It looks after digestive and respiratory tracts

Trap, remove bacteria and foreign substances

Red, swollen, sore = tonsilitis

 

Trap & remove bacterial entering via throat/respiratory tract

 

Lymphatic vessels leave tonsils and enter the cervical nodes
